MACHINE FOR MAKING PAPER WRAPPERS.

Application filed. February 23, 1909.

To all whom it may concern:

Be it known that I, FRANK KAUFMAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Making Paper Wrappers, of which the following is a specification.

The object of the present invention is to construct a machine capable of producing a wrapper for molding, brass tubing, and other similar products, which wrapper consists of a series of sheaths formed from two continuous strips of paper separated from one another by a perforated line.

Another object is to so construct this perforated line that, in tearing the sections -away from one another, the tear will follow the line of perforation and not extend into the body portion of the sheath, and at the same time the line of perforation will be of sufiicient strength so as not to be torn dur ing handling in the course of shipment.

Further objects will appear from a detailed description of the invention, which consists in the features of construction and combination of parts hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of the machine; Fig. 2 a. plan view; Fig. 3 a longitudinal section; Fig. 4: a cross section, taken on line 4 4 of Fig. 3, looking in the direction of the arrow; Fig. 5 a detail of one of the perforating wheels and its carrying` arm; Fig. 6 a plan view of the same; Fig. 7 a cross section of the pasting wheels, showing the spacing collar interposed between two of the wheels; Fig. 8 a detail, showing a portion of the completed wrapper; and Fig. 9 a detail in cross section, showing a piece of molding inclosed in the wrapper.

The machine is mounted upon a framework 10 consisting of a top rail 11, side rails 12, front posts 13, and rear posts 14, the side rails having, at suitable intervals, cross bars 15 located therein. Attached to the forward posts 13 are brackets 16 carrying a. roll of paper 17. The paper, as it is unwound from the roll, passes under an idler 18 located in suitable journals19 upon the top rail of the frame, also passing over an idler 20 held by suitable journals 21, likewise located on the top rail of the frame. The paper then travels rearwardly and passes be- Specieation of Letters Patent.

tween a compression roller 22 and pasting disks 23. The pasting disks revolve loosely upon a fixed shaft 24, said shaft extending beyond the side walls of the top rail 11 and resting in a socket 25 of a. lever 26, which lever is pivoted at a point 27 and is of tapered formation to give it a spring action. The lever is forked at its forward end; and extending through the forked end is a rod 27a which receives a thumb nut 28, and by screwing down this thumb nut the socketed end is thrown upward, thus holding the pasting disks 23 in close and firm contact against the compression roller 22. The pasting disks 23 are adapted tohave their lower ends revolve in a paste box 29, which is held in position by hangers 30 attached to the top rail of the frame, one of the hangers being fixed and the other adapted to be swung loose. As it is, of course, necessary that the sheaths of the wrapper be of varying dimensions, the pasting disks must be adjusted so as to paste any number of strips desired across the width of the paper. This is done by interposing between the pasting disks a loose collar 31. When it is desired to make a wrapper having a sheath of larger dimension, the disks and collars are removed from the shaft, and a collar of greater length is interposed between the disks, thus spacing the disks farther apart.

The compression roller 22 is mounted in a framework 32 located at the rear end and upon the upper surface of the top rail. On the rear end of this frame, and extending crosswise thereof, is a rod 33 which carries a mounting for the perforating wheel, these perforating wheels resting on top of the compression roller 22 at a point in alineinent with the pasting disks 23. The mounting for the perforating wheels consists of a forwardly extending arm 34, forked at its forward end and having an enlarged portion 35 in its center; and extending through the enlarged portion is a screw-threaded rod 36 flattened at its lower end, and the flattened portion is bent to encircle a rod 37 cxtending crosswise of the frame 32. Interposed between the base of the arm 34 and the lower portion of the rod 36 is a. rubber ring or washer 38, and the upper screwthreaded end of the rod 36 is adapted to receive a thumb nut 39. Itwill thus be seen that by adjusting the thumb nut 39 a tension will be placed upon the rubber washer 38, making a frictional contact and preventing the arm 34 from sidewise movement, the looped end of the rod 3b preventing lateral movement. lVhen 1t is desired to move the arm back and forth along the rod 36 to conform with the position of the pasting disks, it can be easily done by loosening the thumb nut 39.

Carried between the forked ends of the arm 84 is a perforating roller 40 having thereon two sets of perforating knives 41-42, the knives being arranged in stag- .gered relation to one another so as to produce a double row of perforations, also in staggered relation to one another, by which arrangement of perforations, the sheaths, when torn apart, will tear along this line and not extend with the body portion of the sheath, as would likely be the case with a single line of perforations.

Located upon the rear post 14 of the framework is a bracket 43 adapted to carry a roll of paper 44, and the paper from this roll is fed over an idler 45 journaled in the side wall of the frame 32 and lying in a position behind the compression roller 22. The paper from the roll 17 and from the roll 44 are thus united on the top surface of the compression roller 22. The paper from the roll 17, having already passed between the pasting disks 23 and the compression roller 22, will have upon its upper surface a strip of paste which will serve to adhere the two separate strips of paper when they are brought together upon the top of the compression roller, and at the same time the knives of the perforating rollers will operate to form a line of perforations along the paper on the line where the paste has been applied. It will be understood that, as the paper is fed forward by the compression roller, the frictional Contact of the paper with the pasting disks and the perforating rollers will serve to rotate both sets of rollers, the peripheries of the perforating rollers serving as a means for bringing the two sections of paper into firm contact and adhering them together.

Extending from the shaft upon which the yompression roller 22 is mounted is a fast and loose pulley connection 46, to which power can be applied, making the compression roller serve as a feed roller for feeding the two sections of paper forward in the desired position. The between the perforating knives, can be passed over the top of the idler 18, if desired, and thence down to a roller suitably located upon the front post 13 of the frame and Wound up.

The operation will be generally understood from the foregoing description, but briefly is as follows: A roll of paper is inserted upon the brackets on either end of the'frame and theirv ends brought forward paper, after passing to the upper portion of the compression roller 22. Power is then applied to the shaft carrying the compression roller and the two strips of paper are carried forward thereby. One of the strips of paper passes between a set of pasting disks and the under side of the compression roller, thus applying a layer of paste to the surface of the paper; and when this paper reaches the top part of the compression roller it adheres itself to the other section of the paper, and at the same time the perforating wheel will act to form perforations between the sheath sections, along the line where the paste has been aplied.

p When it is desired to remove the pasting disks 23 for the purpose of adjustment, the swinging hangers 30 are swung outward and the paste box 29 removed. The thumb screws 28 are then loosened, allowing the lever 26 to swing downwardly, thus lowering the shaft 24 into position where it can be readily removed from the hangers 80.

llhenever it becomes necessary to remove any of the perforating knives from contact with the compression rollers, in order to secure proper adjustment, the same will be accomplished by taking the thumb nut 39 entirely o from the stem 36 and throwing the arm 34 backward, thus carrying the roller 40 out of engagement with the compression roller.
